Method of producing patterned shaped article using scraper

A method of producing a patterned shaped article, the method comprising the steps of:

• forming at least two superposed courses of different dry particles on a base surface;
• moving a scraper located at a prescribed position above the base surface in accordance with a pattern to be expressed so as to scrape at least a lowermost course of said superposed courses, thereby forming a cavity in at least the lowermost course;
• allowing the dry particles of an upper course of said superposed courses to cave into the cavity, thereby expressing the pattern on a bottom surface of the lowermost course;
• making a top surface of the upper course even;
• and
• allowing all the particles to set into an integral mass.

• overlaying a top surface of the upper course with a backing course;
• and
• allowing all the particles and the backing course to set into an integral mass.

• moving a scraper located at a prescribed position above the base surface in accordance with a pattern to be expressed so as to scrape at least a lowermost course of said superposed courses while at the same time removing the particles of at least the lowermost course by suction, thereby forming a cavity in at least the lowermost course;
• allowing the dry particles of an upper course of said superposed courses to cave into the cavity, thereby expressing the pattern on a bottom surface of the lowermost course;
• and
• allowing all the particles to set into an integral mass as they are.
